Patent DE-2342111-A1 (DE)
Title: Ducts formed in foam mattress - while highly compressed thus reducing penetration depth
IPC: B26D1/00
Filed: 1973-08-21
Abstract: A method of making ducts through foam, esp. ventilating ducts through foam mattresses, comprises compressing the foam to a fraction of its original volume in a duct which prevents it from escaping laterally; while thus compressed, the ducts are formed in it, and then the pressure is removed. By thoroughly compressing the foam, the distance through which the duct-forming tools have to operate is considerably reduced and the properties of the initially highly resilient foam are considerably modified to the advantage of the drilling or boring operation.

Title: Tapered bush for connecting hub to shaft - produces clamping and location due to radial expansion and contraction
Inventor: PETER LOTHAR
IPC: F16D1/091
Filed: 1974-02-05
Abstract: A tapered bush in conjunction with two clamp rings is used to provide a concentric and slip proof connection between hub and shaft. Equally spaced screws tie the two clamping rings over the tapers of the mounting bush. This causes a radial contraction of the two tapered ends of the bush, hence the friction resistance created allows torque transmission without slip. The radial expansion of the two clamp rings produces the required friction on the hub bore as well as accurate concentric location. the screws are placed parallel with the shaft and are preferably of the hexagon head variety flush or below the bush end face.
